The rankings represented here are derived via a proprietary algorithm which takes into account not only standard “fantasy points against” metrics, but also weighted averages of separate individual player scouting grades for members of the unit that will be defending, pass rushing, or covering against the position in question.

To use the tool, think about your fantasy player.

Let’s say you own Colts RB Vick Ballard, and would like to see how he matches up against the defense he faces this week. Obviously, Ballard is a flex-type of play who you will be deciding whether to start or sit this week.

First look at the Colts’ matchup for the week, and see what the number is inside the “vs. RBs” cell for their opponent.

Vick Ballard is an RB, and you would like to know his opponent’s rank vs. that position.

As you will see, the Colts are playing the Buffalo Bills, who have a big, blue No. 1 in their “vs. RBs” cell. This is a great indicator for Ballard owners.

Repeat the same process for other players on your roster as you are trying to decide which players to start and which to sit.
